Your Christmas looked like a blast lol! I love the look on your dog's face 😆
I watched all the new Doctor Who specials over the last couple of days, as the Doctor Donna era was one of my favorite arcs, so I really enjoyed seeing them both back again, and holy wow was there a lot of writing acrobatics in all those episodes!

There is "Doctor Who Unleashed" episodes for each of the specials that is the behind the scenes and gives a bunch of the backstory to them getting back together. I found them on torrent sites so not sure if they are available from standard sources since it was air on BBC. The way Russel wrote the third episode we have 2 Doctors now and there could be an entire new series of the Dr/Donna and the continued adventures. The split regeneration was something he always wanted to do.
